百科知识视频之煎蛋小学堂30 那些惊人的真相

We all look forward to the future,but have you ever realized that we only see the past?It actually takes 80 milliseconds for your brain to process information meaning we are never truly living in the now.Not to mention,it takes time for light from an object to reach your eyes.

我们都期盼未来，不过 你曾否意识到我们只能看到过去?大脑处理信息需耗时80毫秒 也就是说 我们永不可能活在当下。更不用说 光到达我们眼内需要时间。

So technically,you see how they looked a fraction of a second ago.Similarly,when you look up at the stars,you are actually seeing light that is taking years to travel to the earth,thus seeing how the stars looked in the past,The next time you are looking,you may want to consider that,That light has traveled all the way through the universe until it bumped into you.

因此 本质上说你看到的是几毫秒前物体的样子。同样 当你仰望星空时，看到的其实是经历数年抵达地球的光，也就是星星曾经的模样。你下次看天空时，也许会想到 这点光在遇到你之前曾划过漫漫长路穿行于宇宙中。

So watch out,Or not,because seconds ago,you were miles away.How?Well the earth is rotating while simultaneously revolving around the sun,But the sun is also spinning around the galaxy which in turn is flying through the universe,making your chance interaction with the light quite incredible.It's sort of puts the sides of the thing into perspective.like the fact that dust particle is roughly half way between the size of earth and subatomic particle.

那么 小心点 其实也不必 因为几秒钟前 你在好几里之外。为什么 其实地球在自转的同时也绕太阳公转。而太阳也在绕星系旋转 那么地球亦是如此，让你和光的交汇变得特别不可思议。这正如放大事物的一个特征。比如灰尘的大小正好处于地球和亚原子大小的中央一样。

Meanwhile,there are more atoms in a glass of water than there are glasses of water in all of earth's oceans.Speaking of oceans,if all the oxygen on the earth disappear for just 5 seconds,the ocean's hydrogen atoms will be free and evaporate completely into space.

另外 一杯水中的原子数量 比所有大洋中 水能盛的杯数还要多。说到大海 如果世界上所有的氧原子消失5秒钟，那海中的氢原子就会蒸发 并全部跑到天空中。

By the way,you can't actually see the Great Wall of China from space.You can, however,see the air pollution,Felling disoriented,if you travel north,you'll eventually go south,but if you travel west,you'll always be traveling west.

另外 在太空中是看不到万里长城的。不过 你能看到雾霾。找不着北了吗 如果你一直往北走 最后会往南行，但如果往西走 距离再长也是向西。

Travel to buy a lottery ticket,and your chance of dying on the way is actually higher than winning.Well,when a pregnant woman suffers organ damage,such as heart attack,the fetus sents stem cells to the damage organ to help repair it.

旅游去买张彩票，你死在半路的可能性比中奖还大。当孕妇器官受损时 比如心脏病发作，胚胎会向受损器官传递干细胞以帮助其修复。

Hot outside?The resting temperature of testicle is around 35°C or 95°F.meaning on a hot day,it's literally hot as balls,Hopefully that made you smile,because even faking a smile stimulates the same part of the brain as a real one,which can trigger endorphines and happiness.

外面太热 蛋蛋的静止温度大概在35℃或95F附近，也就是说 热天热得跟个球似的。希望这能博你一笑 因为即使装笑 也会和真笑一样刺激大脑同一区域，促使内啡酞分泌 让我们快乐。

At the end of the day,humans are just machines that turn energy into ideas,And it turns out that all of history and time has led to you listening to these ideas right now. Thanks for your time.

最后 人类就是将能量转换为想法的机器。结果 一切的时光和历史事件决定了你 在这一刻聆听这些想法。感谢你的这几分钟。
